Future Quantum Hardware

Abstract

Quantum computer hardware is developing rapidly and reaching a complexity that challenges traditional computing. The present hardware is still limited by noisy operations and there is significant systems-level work to get the most out of these devices. I will describe the promise of using quantum error correction to make reliable devices from faulty components and review recent experimental advances in this area. I will then consider the hardware and control challenges of future quantum devices that employ quantum error correction on the scale of hundreds of logical qubits.
